![]() So the computer needs to send signal for driving the mirror and getting back digitized signal from the instrument.Ī plan B would be to chop most of the existing electronics and tap out the analog signal directly from the detector while find a way to drive the mirror by oneself. Doing an FFT on the array one backs out intensity vs. For compound 2, IR spectra were recorded on a Thermo Nicolet Nexus 670 FT-IR spectrometer: For compound 3, IR spectra were recorded on a Thermo Nicolet. My question is, based on these information, would it be possible to decode the signal passed between the card and the instrument? An FT-IR signal is basically an array of intensity vs. Integra, Ever-Glo, Flex-Top, Passport, Import, Seaport, Solid-Substrate, Talon. On the instrument side, there is a 20-pin connector that sends signal to the card. Magna-IR and OMNIC are registered trademarks of Nicolet Instrument. They are probably quite important for communication. I could not identify U1 and U2 sfter a quick search. It looks like this, with a large Xilinx FPGA chip, a Zilog processor, some memory chips and a PLX PCI controller. The instrument sends out signals to a proprietary card in the computer for data processing, mainly FFT, I suppose. It was the work horse of the infrared spectroscopy community. We have a Thermo-Nicolet Nexus 670 FT-IR Spectrophotometer, made in the USA around 2000.
